BLOCK AND CLEVIS FOR LOG-WAGONS.

SPECIFICATION forming part of Letters Patent No. 431,778, dated July 8, 1890.

Application filed March 29, 1890.

To all whom it may concern.-

Be it known that I,WILLIAM H. MILLER, Sr., of \Vyandotte, in the county of Hot Spring and State of Arkansas, have invented a new and Improved Block and Clevis for Log-Wagons, of which the following is a full, clear, and exact description.

My invention relates to improvements in a block and clevis for holding logs in place upon a wagon, sled, car, or other vehicle; and the object of my invention is to provide a simple device by which the logs may -be held in position, and which may be easily operated so as to hold or instantly release the logs.

To this end my invention consists in a triangular block adapted to rest upon the bolster of a vehicle, a clevis pivoted to the bolster'in such a manner that it may be swung upwardly upon the block, and a peculiarlyformed key for holding the clevis in position. This construction will be hereinafter fully described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a bolster mounted upon a wagon-axle and provided with my attachment and with the clevis fastened upon the block; Fig. 2, a broken side elevation of the bolster, block, clevis, and

key; Fig. 3, an end view of the same; Fig. 4,

a detail view of the clevis and clevis-pin; Fig. 5, a detail view of the key by which the clevis is held in position, and Fig. 6 a vertical cross-section on the line 6 6 of Fig. 2.

The bolsters'A A are mounted upon the axle B in the usual manner, and in a logwagon it is well known that thelogs are rolled upon the bolster A. The blocks 0, which are to hold the logs in position upon the bolster and prevent them from rolling off the same are of triangular shape, anda block is mounted upon each end of the bolster A with its inclined side facing inwardly-that is, next the logs. Each block is held in position and prevented from being crowded off the bolster A by a clevis D,which is made, preferably, of fiat metal, and which is pivoted to the bolster Serial No. 345,890. (No model.)

A near the end and near the upper side by a clevis-pin a, which passes through the bolster and through both arms of the clevis near the terminal ends of said arms. The clevis will thus be able to swing vertically upon the pin a over the end of the bolster A. The clevis D has an inwardly-inclined end portion D, so that when the clevis is swung upwardly upon the block 0 it will fit nicely upon the same. The clevis may be swung upwardly upon the block 0 and fastened in this position bya key E, which is of an angular shape, and is made, preferably, of fiat iron. The key E fits in a hole 1) near the upper edge of the bolster A, and has formed upon its upper edge a lug E, which may be moved in the recess 1) in the edge of the hole I), and which will engage the clevis D and prevent. the key from being pushed from the hole I). The key E may be attached to the bolster A by a chain F, so that when not in use it will not be lost.

When the logs are rolled upon the bolster A, they will bear upon the blocks 0, which will be held in place by the clevises D and the keys E, and the logs will be prevented from rolling off. ,There will be but little strain upon the key E, as the logs push the blocks 0 outwardly and the strain will be chiefly upon the clevises D. The vertical portion of the key E will drop into position of its own gravity, and will thus hold the lug E on its upper edge in engagement with the clevis D, so that it cannot be forced out of the hole I).

To unload the logs, the key E is turned up- Wardly, as indicated by the dotted lines in Fig. 2. This will turn the lug E" in the recess b and release it from engagement with the clevis D,so that the pin may be easily removed. Aslight tap upon the clevisD causes it to drop from the block 0, the block is knocked off the bolster A, and the logs may be rolled off in the usual manner.

I have shown my invention as applied to a wagon-axle; but it is obvious that it may be applied to any sort of a Vehicle.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A combined block and clevis for holding logs on vehicles, consisting of a triangular block, a clevis pivoted to the vehicle and lar pin E, adapted to enter the hole I), and adapted toengage the block, and a key prohaving a lug E thereon to engage the clevis IO vided with a lug and adapted to engage the D, substantially as described.
